MOP wnmena.

Application filed April 10, 1922. Serial No. 551,341.

To all whom it may concern:

Be it known that I, FRED A. EATON, a citing at South Stukely, Province of uebec, Canada, have invented certain new and useful Improvements in Mop VVringers; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others'skilled in the art to which it appertainsto make and use the same.

This invention relates to new and'useful improvements in mop wringers.

In the usual mop wringer having a movable back, this back is pivoted'to the rear of the base, and is adapted to be swung forwardly. When the back is thus swung forwardly to squeeze the water out of a mop, there is a greater pressure on the upper part of the mop than on the lower part, the result being incomplete and ununiform wringing. The primary object of this invention is to provide a mop wringer having a back that slides as a whole, rather than one that merely tilts, so that the pressure applied throughout the length of the mop will be equally distributed.

A further object of the invention is a mop having an adjustable front, which, in cooperation with the back, compensates for varying thickness in a mop.

Still another object of the invention is to provide a device of the character indicated above which is inexpensive and economical to manufacture, and efficient in use.

In the accompanying drawings, in which a preferred embodiment of the invention is shown;

Figure 1 is a side elevation of the device applied to a pail;

Figure 2 is a rear View of the wringer;

Figure 3 is a section on the line 33 of Figure 2;

Figure 4: is a view similar to Figure 3, showing the device in operative position;

Figure 5 is a horizontal section on th line -55 of Figure 2;

Figure 6 is a partial front elevation; and,

Figure 7 is a detail of the end of the brace.

Referring to the drawings by reference characters, the numeral 1 indicates a pail or similar vessel to which a mop wringer 2 is applied. The wringer comprises a base portion 3 having drainage slots 4:, and a pair of slotted side members 5 joined by stay rods 6 izen of the United States of AmericaQ resid and secured to the bottom by means of screws A pa1r of legs 8 project downwardly from the side members and form a brace,

terminating in a curved end piece 9 which conforms with the curvature of the vessel and prevents denting of the same when pressure is applied to the wringer. The

' side members are each'provided with a. rearon the vessel. The front 12 of the wringer is pivotally connected with the sides by means of 'trunnions 13. On the innerface I of t-he'front member areformed projections or corrugations 14 over each of which is the upper end of a downwardly inclined slot 15. When these corrugations are pressed against the mop, the water is conveyed downwardly through the slots and into the pail, thus aiding in the emptying of the device. Similar corrugations or slots may be provided for the back member, later to be described. The sides arefurther connected by ,means of a cross bar 16, to which one end of a flat spring 17 is fastened, while the other end of this spring is secured to thelower edge of the front. The function of this spring is to normally hold the front against the forward stay rod 6.

The back member 18 carries spindles 19 at its side edges, which spindles engage and are slidable in the intermediate slots of the sides. A plurality of lugs20 are secured to the back, two above, and one below, the center. To these lugs are secured links 21. A shaft 22 is journalled in the projections 10 and has fixed thereto three links 23 which are in line with the links 21, and have their free ends pivotally attached to the free ends of the links 21, as shown at 24. In the preferred construction here shown, the'links 21'are in pairs joined to opposite sides of the corresponding lugs 20 and links 23. A handle 25 is secured to one end of the shaft outside of the projection 10 and is adapted to turn the shaft. A compression spring 26 joins one of the spindles 19 to one of the projections 10, and serves to withdraw the back to the rear of the wringer, as shown in Figure 2.

In operation, the wet mop is inserted between the back and the front in the usual manner. The handle 25 is pulled forwardly, and the back 18 consequently travels for- Ward on its spindles 19 to the position shown in Figure 4. Any unevenness in the thickness of the mop is taken up by the tilting action of the front 12. WVhen the wring-' ing has been completed, the handle is released and the back travels rearwardly through the action of the spring 26. It is noted in this connection that the drainage of the wringer is very rapid and complete because of the slots in the bottom, the front and the side members.

Vv'hile a specific embodiment of the inven-' tion has been illustrated and described, it is to be understood that various changesin the details of construction may be made without departing from the spirit of the invention as indicated by the appended claims.

Having thus fully described the invention, what I claim asnew and desire to protect by Letters Patent is I l. A mop wringer comprising a frame including a base, a pair of sides and a front, a shaft journalled in said frame, a back slidably supported with relation to the sides,

25 a pair of links secured to the shaft, a link secured to the upper portion of the back and pivoted to one of the first named links, and a link secured to the lower part of the back and pivoted to the free end of the other of said first named links.

2. A mop wringer comprising a frame including a base, a front and a pair of sides, a projection extending rearwardly from each of' said sides, a shaft journalled in said projections, a back slidably supported with relation to thesides, three solid links securedto the shaft, the intermediate link being shorter than the two outside links, a double link pivoted on each side of the upper portion of the back and in line with one of said outside links, said double links having their free ends pivoted tothe free ends ofthe outside links, a double link pivoted to the centre of the lower portion of the back, said double link being in line with the intermediate solid link and having its free end pivoted to the free end of the latter.

In witness whereof I have hereunto set my an -i FRED A; EATON.
